CULTIVATOR.

Specification of Letters Patent. Patented Aug. 30, 1910.

Application filed June.29, 1910. Serial No. 569,512.

To all whom it may concern:

Be it known that I, DUNCAN E. MCDAN- IEL, a citizen of the UnitedStates, residing at Hamel, in the county of Dillon and State of SouthCarolina, have invented a new and useful Cultivator, of which thefollowing is a specification.

This invention has relation to cultivators and consists in the novelconstruction and arrangement of parts as hereinafter shown anddescribed.

The object of the invention is to provide a cultivator of such structureas to be susceptible of a variety of adjustments whereby the implementmay be conveniently and effectually used as a straddle row or betweenrow cultivator and may also be used for harrowing the soil and forbreaking and bedding the fallow soil.

With this object in view the structure includes a frame of peculiarconfiguration with supporting wheels for the same and means for raisingor lowering the frame with respect to the said supporting wheels. Adraft means is attached to the frame and bars are adjustably connectedwith the frame. The said bars carry earth engaging members which may beadjusted with relation to the said bars.

In the accompanying drawings: Figure 1 is a top plan view of thecultivator. Fig. 2 is a transverse sectional view of the lower portionof the same. Fig. 3 is a horizontal sectional view of the same. Fig. 4is a front elevation of the lower portion of the same. Fig. 5 is a sideelevation of the same.

The frame of the cultivator consists of the upper and lower spacedmembers 1 and 2 which are of peculiar configuration and as the saidmembers are of identical shape a description of one will answer forboth. Each of the frame members is provided with an arcuate side portion3 and arcuate portion 4. The portions 3 and 4 are bowed away from eachother and the said portions are each provided with a series ofperforations indicated at 5. The portions 3 and 4 of the frame membersare provided with radially disposed arm qoortions 6 and 7 respectivelyand said arm members 6 and 7 are provided with lug extremities 8 and 9respectively which in turn are provided with perforations indicated at10. The perforations 10 upon the lug extremities 8 are concentric withthe perforations 5 arranged upon the portions 4 of the frame members andthe perforations 10 upon the lug extremities 9 of the arm portions 7 areconcentric with the perforations 5 provided in the portions 3 of theframe members. Bars 11 are provided at their inner ends with bolts 12which are adapted to be passed through the perforations 10 of the lugextremities 8 or 9 of the arm portions 6 and 7 and the said bars 11 areprovided at their outer ends with bolts 13 which are adapted to bepassed through the perforations 5 of the portions 3 and 4 of the framemembers 1 and 2.

As-illustrated in Fig. 3 of the drawing it will be seen that the bolts12 are passed through the perforations 10 carried by the lug extremities8 while the bolts 13 are passed through the perforations 5 provided inthe portions 4 of the frame sections, but it is to be understood thatthe bolts 12 may be passed through the perforations 10 provided in thelug portions 9 of the arms 7 and the bolts 13 may be passed through theperforations 5 provided in the portions 3 of the frame members.

Standards 14 pass vertically through the upper and lower bars 11 and theupper bars 11 are provided in their upper sides with approximatelystar-shaped recesses 15 adapted to receive similarly shaped disks 16fixed to the upper portions of the said standards 14. Boxes 17 are fixedto the lower ends of the standards 14 and carry spindles 18. Disks 19are j ournaled for rotation upon the s indles 18 and the said disks arearrange in pairs with one member of each pair located at the oppositesides of the standards 14 from the other member of the pair carrled bythe said standards. By this arrangement it will be seen that by liftingthe standards 14 so that the star-shaped disks 16 are elevated above therecesses 15 that the said standards 14 may be turned upon their axes andlowered, and when the star-shaped disks 16 again engage the star-shapedrecesses 15 in the upper sides of the uppermost bars 11, the standards14 will be held in fixed position and thus the disks 19 carried by theboxes 17 and spindles 18 may be pitched at any desired angle withrelation to the line of draft of the implement. Also 1t w1ll be seenthat the bars 11 may be adjusted upon the frame members 1 and 2 toassume a great variety of positions and that the inner ends of the saidbars may converge toward each other at the forward or rear port-ion ofthe frame of which the parts 1 and 2 are components.

Blocks 20 are provided with lugs 21 which are inserted betweenthe edgeportions of the members 1 and 2 and secured therein by 'means of bolts22. The said blocks 20 are which is adapted to engage the teeth of aratchet wheel 32. The said ratchet wheel is fixed to the shaft 27 and itwill be seen that by swinging the lever 34 so that the pawl 31 engagesthe teeth of the said wheel the said wheel together with the shaft 27 isrotated and in consequence of such rotation the standards 25 are movedvertically through the blocks 20 and the cross piece 24. Supportingwheels 33 are ournaled for rotation at the lower ends of the standards25 and thus as the said standards are moved the frame of which the parts1 and 2 are components is raised or lowered with relation to thesupporting wheels 33. A ratchet wheel 3% is also fixed to the shaft 27and a holding pawl 35 is pivoted upon the cross piece 2 1 and is adaptedto engage the teeth of the ratchet wheel 3 1 and hold the said shaft 27against rotation after the parts have been properly adjusted.

A standard 36 may be passed vertically through any of the perforations 5of the parts 1 and 2 but as illustrated in Fig. 4c of the drawing it ispreferable to locate the said standard 36 in the perforations 5 midwaybetween the ends of the frame members 1 and 2. The standard 36 at itslower end carries a plow point 37. When the implement is used forcultivating the soil be tween rows it is desirable to apply the standard36 carrying the point 37 but when the implement is used for cultivatingthe soil at the opposite sides of a row the said standard 36 carryingthe point 37 is removed when the implement may be used in a straddle rowmanner. A draft frame 38 may be attached to the portions 3 or a of theframe members 1 and 2 and the rear end of a draft tongue 39 is attachedto the said draft frame 33. The standard 36 is provided with forwardlydisposed arms 40 and when the said standard 36 is attached to the frameof which the parts 1 and 2 are components the rear end portion of thedraft tongue 39 is connected with the arms 4-0 by means of a pivot bar41 which passes transversely through the said arms and through the rearportion of the said tongue 39.

From the above description it will be seen that the parts of thecultivator are susceptible of a great variety of adjustments and byreason of this variety the parts may be positioned so as to effectuallyoperate upon soils of different characters and for producing desiredeffects in the soil irrespective of its conditions.

What is claimed is:

1. A cultivator comprising a frame consisting of spaced. members havingoppositely disposed arcuateportions with radially disposed arm portions,bars adapted to be adjustably connected with the arcuate and armportions of the frame members, standards carried by the bars, earthengaging members carried by the standards, supporting wheels for theframe, and means for raising and lowering with relation to saidsupporting wheels.

2. A cultivator comprising a frame consisting of spaced members havingoppositely disposed arcuate portions and arm portions, bars adapted tobe adj ustably connected with the arcuate portions and arm portions ofsaid frame members, some of the said bars having non-circular recesses,standards passing transversely through the bars and having non-circulardisks adapted to fit within said recesses, earth engaging memberscarried by the standards, supporting wheels for the frame, and means forraising and lowering the frame with relation to the support ing wheels.

3. A cultivator comprising a frame consisting of spaced members havingoppositely disposed arcuate portions and oppositely disposed armportions, bars adapted to be adjustably attached to the arm portions andarcuate portions of the frame members, standards carried by the bars,earth engaging members carried by the standards, blocks located at theends of the frame members, standards slidably mounted in said blocks,supporting wheels journaled in the lower ends of said standards, andmeans for moving the said standards through the blocks.

In testimony that I claim the foregoing as my own, I have hereto atlixedmy signature in the presence of two witnesses.
